Section properties: I_t, I_ω, shear centre (FEM)

About this calculation

Area, second moments, elastic and plastic moduli, principal axes, torsion constant, shear centre, warping constant and sectorial coordinate of any section: built up from catalogue profiles, plates and tubes, given by coordinates or imported from DXF.

Design basis

Finite element method: Saint-Venant torsion, Vlasov warping properties; EN 1993-1-1; SP 16.13330.2017; AISC 360-22
